Frequently Asked Questions
What does a heading hierarchy checker do?▾
It checks the order and clarity of H1-H6 headings in pasted HTML so you can spot multiple H1s, skipped levels, empty headings, and weak page structure before publishing.
Should every page have one H1?▾
Most pages should have one clear H1 that names the main topic. Supporting sections can then use H2, H3, and deeper levels only when the structure needs them.
Are skipped heading levels always bad?▾
Not always, but jumps like H1 straight to H3 can make the page structure harder to scan for users and search engines. Clean hierarchy is usually the safer default.
Does a good heading outline guarantee rankings?▾
No. It improves structure and usability, but rankings still depend on search intent, page usefulness, technical health, and competition.
When should I use this tool?▾
Use it before publishing a new page, after a major refresh, or when GSC shows impressions but the page still feels hard to scan and understand.
